Ultrasound detection of emboli in blood stream
29 June 2006
Luna Innovations Incorporated (Nasdaq: LUNA) has developed
a device that uses quantitative ultrasound technology to non-invasively
count emboli in the blood stream.
The Luna EDAC (embolus detection and classification) Quantifier system
uses missile-tracking algorithms to analyse ultrasound data to detect
individual microemboli in the blood at rates up to 1000 per second.
The system is designed to provide cardiothoracic surgeons, perfusionists
and anaesthesiologists with an accurate rate of emboli in the blood circuit.
Emboli can be air bubbles or solid matter (eg lipid, blood clot) and can
enter the blood circuit during critical and invasive medical procedures such
as a cardio pulmonary bypass surgery. Emboli can be dangerous causing
neurological or neuropsychological postoperative deficits and in some cases
The initial release of the EDAC Quantifier system was launched
in May at Outcomes 2006 in Key West, Florida and is "for investigational use
only." Luna is currently accepting orders for research and exploration
